About prevalence and incidence statistics:

The term 'prevalence' of Isovaleric Acidemia usually refers to the estimated population of people who are managing Isovaleric Acidemia at any given time. The term 'incidence' of Isovaleric Acidemia refers to the annual diagnosis rate, or the number of new cases of Isovaleric Acidemia diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
